Mata says he's loving life at the London giants.
He told Chelsea magazine: "I am really, really happy and very proud - it is the best feeling in the world to feel loved by the supporters and my team-mates. It has made my year perfect.
"You can't ask me to choose between them! The players one is very special because they are my team-mates and they see me every day. Together, we share the good and bad moments, so that makes it a big honour to be voted by them. The supporters one, meanwhile, is from everybody who watches Chelsea from every part of the world. They are the heart of the club."
